Bang and Olufsen have released the Beolab5 loudspeakers that calibrate themselves according to the acoustics within the room, and have a acoustic lenses to create a flat directivity pattern. The acoustic lense technology is licensed from Sausolito Audio Works.
See the specifications on the Bang and Olufsen web site.
Microstrain announced the availability of miniature wireless sensors called EmbedSense. EmbedSense uses an inductive link to receive power from an external coil and to return digital strain, temperature and unique ID information

ESI Group have announced the release of AutoSEA 2003. AutoSEA2 2003 includes a new general laminate subsystem with visco-elastic material properties, enables predictions of the damping added by acoustic treatment layers, including foam-backed carpet, dash barriers and headliner trims, and now supports object grouping and provides new features for model quality checking. To help diagnose the noise paths and to identify the design parameters which are controlling the predicted noise levels, the energy level “thermogram” has been enhanced.

It has been one year since noiseboard.com was started. There have been over 36,000 hits over the year. The tallys in the download section show that many people find the articles and papers useful. If you do find something useful, please don’t hesitate to drop me a note (and no, your email or fake email address will not get onto a spam list.)
I am currently preparing a short article that compares the use of ANSYS for acoustic analyses using a P4 computer, with and without the Hyperthreading, under windows and Linux, using version 7 and an older version. The first results show that there is little difference between HT and not HT, but a big difference between an older version and V7.0.
